Minimal Soil Impacts of Caesalpinia decapetala Invasion in South Africa's Vhembe Biosphere Reserve

African Journal of Ecology, Volume 63, Issue 2, March 2025.
ABSTRACT We assessed the effects of Caesalpinia decapetala (Roth) Alston invasion on soil physical properties over 3 summer months in Vhembe Biosphere Reserve, South Africa. Topsoils were collected beneath replicated invaded and uninvaded conditions and assessed for soil moisture, water repellency, penetration resistance, infiltration and hydraulic ...

Patterns of soil water repellency change with wetting and drying: the influence of cracks, roots and drainage conditions [PDF]

, 2014
The influence of simulated cracks and roots on soil water repellency (SWR) dynamics with and without basal drainage impedance in wetting–drying cycles was investigated in the laboratory experiments.

Biochar impacts on soil moisture retention and respiration in a coarse‐textured soil under dry conditions

Soil Science Society of America Journal, Volume 88, Issue 6, Page 1919-1931, November/December 2024.
Abstract The growing water scarcity jeopardizes crop production for global food security, a problem poised to worsen under climate change–induced drought. Amending soils with locally derived biochar from pyrolyzed agricultural residues may enhance soil moisture retention and resilience, in addition to climate change mitigation.

Does drought alter hydrological functions in forest soils? [PDF]

Hydrology and Earth System Sciences, 2016
Climate change is expected to impact the water cycle and severely affect precipitation patterns across central Europe and in other parts of the world, leading to more frequent and severe droughts.

Preliminary experiments of soil hydrophobic character with krüss dsa drop shape analyser [PDF]

, 2023
In our experiments, we used Krüss DSA 100 drop shape analyzer to test the wettability of different Hungarian soil and sediment samples, which measures the contact angle (cA) and water drop penetration time (WDPT), excellent indicators of the wettability ...

Quantitative experimental study on the apparent contact angle of unsaturated loess and its application in soil–water characteristics curve modeling

Vadose Zone Journal, Volume 23, Issue 6, November/December 2024.
Abstract Advancing and receding water contact angles, often denoted as the maximum and minimum apparent water contact angles, are crucial parameters reflecting a soil's water holding capacity. These parameters play an important role in establishing theoretical soil–water characteristic curves (SWCCs) for unsaturated soils.

Continuous Monitoring of Vegetation and Soil Recovery After Eucalyptus grandis Removal in Dense Trees and Shrubs Areas

African Journal of Ecology, Volume 62, Issue 3, September 2024.
ABSTRACT Invasion by invasive alien plants is a global challenge and South Africa has invested billions of Rands to manage invaders through the Working for Water programme. However, regular monitoring after alien plant clearing is hardly done, yet it forms the basis for assessing clearing programme effectiveness, particularly ecosystem recovery ...

Impact of secondary succession in abandoned fields on some properties of acidic sandy soils [PDF]

, 2020
Abandonment of agricultural lands in recent decades is occurring mainly in Europe, North America and Oceania, and changing the fate of landscapes as the ecosystem recovers during fallow stage.

Development of a universal microinfiltrometer to estimate extent and persistence of soil water repellency as a function of capillary pressure and interface chemical composition [PDF]

, 2020
Microinfiltrometers to assess soil water repellency (SWR) are limited to small tension ranges and have different technical setups, hindering a comparison between results from different laboratories.
